EGG CARTON. z

Application filed January 17, 1922. Serial No. 529,889.

To all whom it may concern Be it known that I, ALBERT Rnrznn, a citizen of the United States, and resident of Milwaukee. in the county of Milwaukee and State of isconsin, have invented certain new and useful Improvements in Egg Cartons, and I do hereby declare that he following is a full, clear, and exact description thereof.

My invention relates to an egg carton of the type which may be used by retailers for conveniently delivering eggs in small quantities to the consumer.

The general object of the invention is to provide a carton which is formed from a single strip of material which may previously be pressed into suitable shape by the manufacturer and nested in large numbers for convenience in shipping.

A further object of the invention is to re duce the cost of manufacture of these articles to conserve the material, and at the same time provide a carton which is easily folded together from a blank and which will securely protect the eggs against breakage.

The invention will be described in connec tion with the accompanying drawing, in which- Figure 1 is a cross sectional view of the ably scored along its transverse median line 6, so as to form a flexible hinge which will connect the two complementary halves of the carton. The portion adjacent the median line is suitably pressed into a shape to provide rounded edges 7 and 8, and is scored on the line 9 where it is turned inwardly and extends centrally across from side to side of the carton in juxtaposition to the corresponding portion of the other half. The

' strip is again scored on the line 10 and the end portion 11 is pressed substantially into the shape of a half cylinder which extends tangentially to the top or bottom wall of the carton and terminates at the median line of the juxtaposed portions and perpendicular thereto. Each half of the strip between the lines 9 and 10 is formed with series of radially disposed tongues 13, which are pressed outwardly to form pockets for the eggs, as shown.

It will be understood that any v suitable means may be provided for securing the carton in closed position, as represented in Figure 1.

From the foregoing description, it will be seen that I have invented a simple and practical device which may be manufactured at a minimum cost and with a minimum amount of material.

It will also be noted that the corners 7 and 8, which are previously pressed into the correct shape, and also the reinforcement provided by the semi-cylindrical portions 11, will ensure a substantial protection to the eggs and insure their delivery with very little danger of breakage.

I claim:

1. As an article of manufacture, an egg carton formed from a single strip of material folded so that the intermediate portion of the strip forms the top, bottom and sides of the carton, the ii itermediate portions of j the strip meeting centrally of one side of the carton and extending in juxtaposed relation, to the central line of the other side, and thence outwardly in opposite directions and forming a pair of semioylindrical surfaces tangent to the top and bottom walls of the carton respectively and meeting the central line of the juxtaposed portions substantially at right 'angle 2. As an article of manufacture, an egg carton formed from a single strip of material folded so that the intermediate portion of the strip forms the top, bottom and sides of the carton, the next adjacent portions of the strip extending in juxtaposed relation from side to side of the carton and having tongues cut therefrom-to form opposed cavities, the free end portions of the strip beyond the egg receiving portions, each being pressed into semicylindrical form and disposed so as to extend aroundone row of eggs, and terminating at the central line of the juxtaposed portions.

3. As an-articleof manufacture, an egg carton formed from a strip of material folded so that the intermediate portion of the strip forms the top, bottom and sides of the carton, the next adjacent portions of the strip extending in juxtaposed relation from side to side of the carton and having rows of openings cut therein for the reception of eggs, the free end portions of the strip beyond the egg receiving portions each being a-rcuately curved and disposed so as to extend around one row of eggs and terminate at the juxtaposed portions between the rows.

In testimony that 1 claim the foregoing I 10 have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of Ti'iseonsin.

ALBERT RETZER.
